5 Parameters
5.4 I/0 control
98 DC1 variable frequency drive 12/13 MN04020003Z-EN www.eaton.com
5.4 I/0 control
Parameter P-15 is used to configure the mode of operation and function of
both the digital and analog inputs. The configured value will depend on
parameter P-12.
Figure 61: Digital and analog inputs
The operation of the DC1 variable frequency drive's via control signal termi-
nals (P-12 = 0, P-15 = 5) is active with factory settings:
• DI1 (control signal terminal 2): FWD (Start enable clockwise rotating
field)
• DI2 (control signal terminal 3): REV (Start enable anti-clockwise rotating
field)
• DI3/AI2 (control signal terminal 4): FF1 (fixed frequency 1= P-20;
WE = 15 Hz)
• AI1/DI4 (control signal terminal 6): analog setpoint input (0 - 10 V)
When control control signal terminal 2 (FWD) and control signal terminal 3
(REV) are activated at the same time, a dec2 (P2-24) quick stop will be
activated.
In the case of variable frequency drives with local controls (DC1-…-A6SN),
the FWD switch position will drive DI1 and the REV switch position will
drive DI2.

The FWD and REV designations refer to the default settings.
The above functions may change if changes are made to the
P-15 parameter.
